tension= weight held up= weight chain below+ weight bolder tension= (790+600)g That is the tension at the top, and of course, the tension at the bottom is 790g, so tension varies on the length. If it breaks, it is at the top. Here, tension cannot be greater than 3*600*g. Is it?

PHYSICSSSSS helpppp please
If they are sliding at the same rate, tension is zero. If they are not sliding, then there is tension.
